Abstract
Description
Technical Field
[0001] This application relates to the field of damage assessment technology, and in particular to damage assessment methods, devices and storage media for pressure swing adsorption devices. Background Technology
[0002] With the rapid development of industry and energy sectors, adsorbers, as important equipment, are widely used in gas separation, storage, and purification. Their use is becoming increasingly common, especially in hydrogen-rich environments. However, the fatigue damage caused by hydrogen-rich environments to adsorber materials is becoming increasingly significant. The unique characteristics of this environment make adsorbers prone to performance degradation and even equipment failure during long-term operation, posing a significant challenge to the reliability and safety of adsors.
[0003] Currently, existing damage detection methods mostly focus on monitoring a single parameter, such as temperature, pressure, or vibration. However, these single detection methods often cannot comprehensively and accurately assess the actual damage to the adsorber under complex operating conditions. Especially under the combined effects of hydrogen-rich environments and alternating loads, a single detection method is insufficient to fully reflect the evolution of damage. Therefore, there is an urgent need to adopt a comprehensive assessment approach that combines multiple detection technologies to monitor different damage modes of the adsorber in real time, thereby improving the accuracy and sensitivity of damage detection. These detection technologies can perform quantitative analysis of the adsorber from multiple dimensions, providing more accurate data support for damage assessment.
[0004] In summary, existing technologies suffer from limitations due to the reliance on single detection methods, which prevent a comprehensive and accurate assessment of the actual damage to the adsorber under complex operating conditions, further impacting the reliability of damage identification. Summary of the Invention

It should also be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings, not all of them.
[0018] Example 1, please refer to the appendix. Figure 1This application provides a damage assessment method for a pressure swing adsorption (PSA) device, applicable to a damage assessment device for a PSA device, specifically including the following steps:
[0019] Step 1: Collect the operating data of the pressure swing adsorption device in real time through the sensor system, input the operating data into the damage assessment model to monitor the condition of the pressure swing adsorption device, and obtain the condition monitoring results.
[0020] Specifically, the pressure swing adsorption (PSA) unit's operational data is collected in real time through a sensor system. First, the sensors monitor and record the operating parameters of key components, such as pressure, temperature, flow rate, and gas concentration. This data reflects the unit's actual operating status. For example, a decrease in gas flow rate in the adsorption bed may indicate a decline in adsorption capacity or blockage. Next, this real-time operational data is input into a damage assessment model. By analyzing the input data, the model identifies signs of damage or malfunction. For instance, abnormal fluctuations in the temperature and pressure of the adsorption bed may indicate agglomeration or damage. Finally, the output of the damage assessment model is used for status monitoring. The system assesses the equipment's health status and generates monitoring results. For example, when the equipment's health status score falls below a set threshold, the system may issue an alert, reminding the operator to perform maintenance or adjustments.
[0021] Step 2: Based on the monitoring results in the condition monitoring results, damage pattern identification is performed to obtain damage pattern data.
[0022] Specifically, based on the monitoring results in the condition monitoring report, firstly, the condition monitoring results include various operational data of the pressure swing adsorption (PSA) unit, such as real-time values of temperature, pressure, and flow rate. These data reflect the operating status of the unit. Next, by performing damage mode identification on these monitoring results, the system can analyze different damage modes. For example, if the equipment operates under high-temperature conditions and pressure fluctuations occur, this may be an indication of seal damage. By analyzing the data change trends in the monitoring results, the system can identify the potential causes of damage behind these changes. Damage mode data refers to data information obtained during the analysis process that indicates the type of equipment damage, such as possible seal damage, adsorption bed blockage, or other internal faults. This damage mode data can further guide maintenance personnel to take appropriate repair measures to ensure the normal operation of the equipment.
[0023] Step 3: Based on the injury pattern data, conduct a health status assessment to obtain the health assessment results.
[0024] Specifically, health status assessment based on the damage pattern data first requires understanding that this data is derived from monitoring and analyzing the equipment's operating status, revealing the specific extent of damage. By inputting this damage pattern data into the health status assessment model, the system combines it with the equipment's normal operating standards to evaluate its current health status. For example, if the equipment's sensors detect excessively high temperatures or excessively low pressures, this damage pattern data will be used to determine whether the equipment is excessively worn or damaged. The health status assessment result, based on this analytical data, concludes whether the equipment requires maintenance and whether it can continue to operate safely.
[0025] Step 4: Continuously monitor the pressure swing adsorption device based on the health assessment results.
[0026] Specifically, continuous monitoring of the pressure swing adsorption (PSA) device based on the health assessment results means that after completing the initial health status assessment, the system will determine whether long-term, continuous monitoring of the PSA device is necessary based on the assessment results. For example, if the assessment results show that the device is in high health, the monitoring frequency can be reduced, and checks can be performed only during critical periods. However, if the assessment results show that the device is in low health, the monitoring frequency needs to be increased, and various operating parameters of the device, such as temperature, pressure, and flow rate, may be tracked in real time. The purpose of continuous monitoring is to identify potential problems in advance before equipment failure occurs, thereby avoiding sudden shutdowns or major damage to the equipment. Through this continuous monitoring, it is possible to ensure that the equipment remains stable during long-term operation, promptly detect possible faults, and take corresponding maintenance measures, thereby extending the service life of the equipment.
[0027] The damage assessment method for the pressure swing adsorption (PSA) device can be applied to the damage assessment device of the PSA device to achieve the technical goal of multimodal quantitative detection, so as to achieve comprehensive and accurate monitoring of adsorber damage, improve the reliability of damage identification, and thus effectively extend the service life of the equipment and ensure the safe operation of the equipment.
[0028] Furthermore, this application also includes: introducing an adaptive calibration mapping relationship, performing device status identification on the initial sensor system by collecting real-time data to obtain a real-time status, wherein the adaptive calibration mapping includes a mapping relationship between device data and device status; performing device health identification on the initial sensor system based on the real-time status to obtain a sensor repair strategy; and repairing the initial sensor system according to the sensor repair strategy to obtain the sensor system.
[0029] Specifically, adaptive calibration mapping is a dynamic adjustment mechanism that calibrates equipment based on real-time data to minimize the error between the measured results and the actual state. By collecting real-time data, the system can reflect the current operating status of the equipment, such as temperature, pressure, or vibration. Then, through equipment status recognition technology, the system infers the actual operating condition of the equipment based on this data, such as whether the equipment is normal or whether there are signs of malfunction. Real-time status refers to the health and performance status of the equipment at the current moment. For example, if the equipment temperature exceeds a set range, the system will determine it as an abnormal state. Adaptive calibration mapping provides a mechanism for real-time adjustment and optimization of equipment monitoring by mapping the relationship between the equipment's operating data and its status, thereby ensuring the accuracy of equipment status monitoring.
[0030] After obtaining real-time status, the system performs a health assessment based on the device's current condition, such as analyzing whether the device's temperature and pressure are within normal operating ranges. If the device's health status indicates a potential risk of failure, the system initiates a device health identification procedure to assess whether the device requires repair. Sensor repair strategies are solutions proposed by the system to improve or restore sensor functionality. For example, if a sensor drifts, causing inaccurate data, the system may recommend recalibrating or replacing the sensor. Implementing this strategy helps ensure the accuracy and reliability of the device, preventing sensor failures from impacting the overall performance of the device.
[0031] After developing a sensor repair strategy, the next step is to execute the actual repair work. For example, following the repair strategy might involve cleaning, recalibrating, or replacing damaged sensor components. Through these repair measures, the system can restore the sensor's functionality, enabling it to provide accurate data output again. Ultimately, the repaired sensor system returns to normal operation, ensuring the equipment can continue to monitor and control various operating parameters, thus achieving long-term stable operation.
[0032] Furthermore, this application also includes: collecting historical operating data and fault records to construct the damage assessment model, wherein the damage assessment model includes a pressure analysis channel, a temperature analysis channel, a flow analysis channel, and a concentration analysis channel; extracting pressure fluctuations from the operating data, inputting them into the pressure analysis channel, and performing pressure fluctuation analysis to obtain pressure monitoring results; extracting temperature fluctuations from the operating data, inputting them into the temperature analysis channel, and performing temperature fluctuation analysis to obtain temperature monitoring results; extracting gas flow rates from the operating data, inputting them into the flow analysis channel, and performing gas flow analysis to obtain flow monitoring results; extracting gas concentrations from the operating data, inputting them into the concentration analysis channel, and performing gas concentration analysis to obtain concentration monitoring results; and combining the pressure monitoring results, the temperature monitoring results, the flow monitoring results, and the concentration monitoring results to obtain the status monitoring results.
[0033] Specifically, collecting historical operational data refers to data obtained from the long-term operation of equipment or systems. This data reflects the equipment's performance at different times. For example, historical records of indicators such as pressure, temperature, and flow rate help us understand the equipment's normal and abnormal states. Meanwhile, fault records refer to information related to faults that occur during equipment operation, such as fault type, occurrence time, and duration. This information helps analyze potential problems with the equipment. By collecting this data, a damage assessment model can be built. This model includes different analytical channels, such as pressure, temperature, flow rate, and concentration analysis channels. These channels correspond to the monitoring and analysis of different parameters in the equipment. Each channel's function is to perform in-depth analysis of specific variables, thereby assessing the equipment's health status.
[0034] Next, during the damage assessment process, pressure fluctuation information is first extracted from historical operating data. Pressure fluctuation refers to the change in pressure value over time during equipment operation. If the pressure change exceeds the normal design range of the equipment, it may lead to damage. After extracting this fluctuation data, it is input into the pressure analysis channel, which is specifically used to analyze the pressure change pattern. By analyzing pressure fluctuations, the system can identify whether there are abnormal pressure fluctuations in the equipment, and thus obtain pressure monitoring results. These results help assess the risk of equipment damage due to abnormal pressure.
[0035] Temperature fluctuations refer to changes in the temperature of equipment during operation. For example, excessively high temperature fluctuations within a certain period can lead to equipment damage. By extracting temperature fluctuation information from historical operating data and inputting it into a temperature analysis channel for detailed analysis, the system can identify abnormal temperature trends or situations. Ultimately, after temperature fluctuation analysis, the system can obtain temperature monitoring results, which helps determine whether the equipment is within its normal temperature range, thereby ensuring its safe operation.
[0036] Gas flow fluctuations refer to the changes in gas flow rate over time during equipment operation. If flow fluctuations exceed the normal range, it may indicate a problem with a component of the equipment. By extracting flow data from historical operating data and inputting it into the flow analysis channel, the system can perform detailed flow analysis. Flow analysis helps the monitoring system identify any flow anomalies, thereby determining whether the equipment is operating normally. Ultimately, the analysis results provide flow monitoring findings to help assess the health status of the equipment.
[0037] Changes in gas concentration can affect equipment efficiency or indicate leaks or blockages within the system. By extracting gas concentration information from operational data and inputting it into a concentration analysis channel, the system analyzes concentration trends. This process helps identify whether gas concentrations are within normal ranges, obtains concentration monitoring results, and further aids in assessing potential equipment malfunction risks.
[0038] Finally, the system comprehensively analyzes the results obtained from pressure monitoring, temperature monitoring, flow monitoring, and concentration monitoring. By combining the monitoring results of these different parameters, the system can comprehensively assess the status of the equipment. If any parameter is abnormal, the system will issue a warning, indicating a potential risk of equipment failure. The analysis of multiple monitoring results provides a more accurate reflection of the overall health of the equipment, thus providing strong support for maintenance and repair.
[0039] Furthermore, this application also includes: performing valve deformation detection on the pressure swing adsorption device to obtain a first detection result; evaluating the stability of pipe and joint connections on the pressure swing adsorption device to obtain a second detection result; identifying wear on the adsorption bed structure of the pressure swing adsorption device to obtain a third detection result; performing airtightness detection on the first detection result, the second detection result, and the third detection result according to an airtightness judgment threshold, and collecting the operating data based on the airtightness results.
[0040] Specifically, valves in pressure swing adsorption (PSA) devices are crucial components controlling gas flow, and their deformation can lead to limited gas flow or equipment failure. Valve deformation detection involves measuring and analyzing the valve's geometry to check for deformation caused by pressure, temperature changes, or other external factors. Detection methods can include using sensors, displacement gauges, and other tools to collect valve deformation data in real time, ensuring the valve remains operational. The initial detection result is the degree of valve deformation, which indicates whether the valve requires repair or replacement.
[0041] Secondly, the piping and joint connections of the pressure swing adsorption (PSA) unit are crucial for ensuring smooth gas flow. The stability of the piping and joints affects the system's airtightness and overall operating efficiency. Evaluating the stability of piping connections includes checking for cracks, loosening, and leaks, while ensuring the stability of joint connections guarantees that all connections are free from leaks, loosening, or detachment. Pressure testing and vibration analysis can determine whether the piping and joints can withstand long-term operating loads, ensuring safe equipment operation. The second test result is the stability evaluation of the piping and joint connections, which helps assess the equipment's reliability and maintenance needs.
[0042] Next, the adsorption bed is the core component of the pressure swing adsorption (PSA) unit, its main function being to adsorb impurities from the gas. During long-term use, the adsorption bed may wear down, leading to reduced adsorption efficiency and even affecting the overall performance of the equipment. Therefore, adsorption bed structural wear identification involves inspecting the surface, pores, and overall structure of the adsorption bed to determine if cracks, damage, aging, or other defects are present. The degree of wear on the adsorption bed can be obtained in real time through methods such as vibration analysis, acoustic wave detection, or temperature monitoring. The third test result is an assessment of the adsorption bed's wear condition, which helps determine whether the adsorption bed needs to be replaced to restore the equipment's adsorption efficiency.
[0043] Finally, airtightness is a crucial indicator for evaluating the safety and efficiency of a pressure swing adsorption (PSA) unit. Based on a preset airtightness threshold, the system combines the first, second, and third detection results to assess the overall airtightness of the equipment. If valve deformation, pipe joint stability, and adsorption bed wear meet airtightness requirements, it indicates that the equipment maintains good sealing performance and prevents gas leakage. If the detection results indicate problems, the airtightness assessment will warn of potential leakage risks. Based on the airtightness assessment results, the system further collects data related to equipment operation for real-time monitoring and early warning, ensuring the normal operation of the equipment.
[0044] Furthermore, this application also includes: extracting pressure monitoring results based on the status monitoring results, identifying adsorption bed blockage in the pressure swing adsorption device according to a preset pressure fluctuation, and obtaining adsorption bed monitoring results; extracting temperature monitoring results based on the status monitoring results, performing adsorption-desorption function testing on the pressure swing adsorption device according to a preset temperature range, and obtaining function monitoring results; extracting flow monitoring results and concentration monitoring results based on the status monitoring results, identifying adsorbent agglomeration in the pressure swing adsorption device according to a preset decreasing trend, and obtaining adsorbent monitoring results; and combining the adsorption bed monitoring results, the function monitoring results, and the adsorbent monitoring results to obtain the damage mode data.
[0045] Specifically, pressure data extracted from the condition monitoring results can detect abnormal pressure fluctuations in the system. Pressure fluctuations may indicate blockage or obstruction in the adsorption bed, which typically leads to restricted gas flow and reduced equipment efficiency. By comparing the detected pressure fluctuations to a preset range, if the fluctuations exceed the normal range, it can be determined whether the adsorption bed is blocked. After identifying adsorption bed blockage, the system outputs the adsorption bed monitoring results, providing diagnostic information on whether the equipment is blocked.
[0046] Secondly, in pressure swing adsorption (PSA) devices, adsorption and desorption typically occur under specific temperature conditions, making temperature fluctuation monitoring crucial. Temperature data extracted from condition monitoring results allows determination of whether the equipment operates within a preset temperature range. If the temperature exceeds the normal operating range, it may affect the adsorption and desorption processes, leading to equipment malfunction. Therefore, the system analyzes the temperature data and performs adsorption and desorption function tests based on the preset temperature range. Based on the test results, the system outputs a function monitoring result, determining whether the equipment is operating normally.
[0047] Next, flow rate monitoring results reflect the gas flow state, while concentration monitoring results reflect the gas purification effect during adsorption. An abnormal drop in flow rate or concentration may be due to adsorbent agglomeration, leading to a decrease in the performance of the adsorption device. Therefore, by analyzing the flow rate and concentration monitoring data and comparing them with a preset downward trend, the system can identify whether adsorbent agglomeration exists. Adsorbent agglomeration affects gas adsorption efficiency; therefore, by identifying this phenomenon, the system can obtain adsorbent monitoring results to guide equipment maintenance.
[0048] Finally, damage mode data is crucial information reflecting the overall health status of the pressure swing adsorption (PSA) unit. By combining adsorption bed monitoring results, functional monitoring results, and adsorbent monitoring results, a comprehensive assessment of the equipment's operating status can be achieved. For example, if the adsorption bed becomes clogged, its function is affected by temperature fluctuations, or the adsorbent clumps, all these issues will impact the overall efficiency and lifespan of the equipment. By comprehensively analyzing this monitoring data, the system can obtain accurate damage mode data to determine whether the equipment has potential faults or damage.
[0049] Furthermore, this application also includes: extracting the temperature change trend of the pressure swing adsorption device based on the preset temperature range to identify adsorption anomalies and obtain leakage detection results; identifying poor heat transfer of the pressure swing adsorption device based on its internal structure and verifying the leakage detection results to obtain leakage verification results; and using the leakage verification results as the functional monitoring results.
[0050] Specifically, temperature change is a critical parameter in pressure swing adsorption (PSA) devices because it directly affects the efficiency of adsorption and desorption processes. The system monitors temperatures within a preset range; if the temperature change trend deviates from the preset normal range, it indicates a potential anomaly. For example, during operation, the temperature typically changes with the adsorption and desorption process. If the temperature change is too rapid or too slow, it may indicate abnormal heat exchange due to gas leakage during adsorption. By extracting the temperature change trend of the device, the system can identify whether adsorption anomalies exist and generate leak detection results based on this identification.
[0051] Next, the internal structure of the pressure swing adsorption (PSA) device affects its heat transfer efficiency. Defects or poor design in the internal heat transfer system can lead to uneven temperature distribution or low heat transfer efficiency, thus impacting the performance of the entire adsorption process. By analyzing the internal structure, the system can identify any instances of poor heat transfer. Poor heat transfer can exacerbate leaks, therefore, the leak detection results from the previous step need to be verified. If heat transfer problems exist, the leak detection results may be inaccurate. By verifying the leak detection results, the system can obtain a more accurate leak verification result, ensuring that there is no actual leak in the device.
[0052] Finally, leak verification results are one of the important bases for equipment health monitoring. Leak verification results not only confirm whether a leak has occurred in the equipment, but also reflect the overall functional status of the equipment. If leak verification results indicate a leak, the equipment's functionality may be severely affected, leading to reduced work efficiency or decreased safety. Therefore, leak verification results directly serve as functional monitoring results, providing a basis for judging whether the equipment is operating normally.
[0053] Furthermore, this application also includes: obtaining the impact of the injury pattern data on health status and configuring injury weights; performing a weighted calculation of the injury pattern data according to the injury weights to obtain a health status score; and using the health status score as the health assessment result.
[0054] Specifically, in the condition monitoring of pressure swing adsorption (PSA) units, damage mode data reflects the health status of various parts of the equipment. For example, different components of the equipment, such as the adsorption bed, valves, and pipelines, may experience different types of damage during long-term operation. Each damage mode may have a different impact on the overall health of the equipment, requiring us to configure damage weights based on the specific impact of each damage mode. Damage weight refers to the degree of importance of different types of damage when assessing the health status of the equipment. If a damage mode has a significant impact on equipment performance, its damage weight will be higher. By acquiring this damage mode data and its corresponding impact, we can more accurately assess the health status of the equipment.
[0055] Based on the configured damage weights, we perform a weighted calculation on the data for each damage mode. The weighted calculation process involves multiplying the data for each damage mode by its corresponding damage weight and then summing the results. Through this calculation, we obtain a comprehensive health status score, which reflects the overall health of the equipment. For example, if a component has a high damage weight and its damage level is also high, then this component will have a greater impact on the health status score, thus lowering the overall health score of the equipment. Through this weighted method, the health status score can comprehensively reflect the health status of all components of the equipment.
[0056] Ultimately, the weighted health status score is the health assessment result, providing crucial information for equipment maintenance and repair. This score helps managers determine the current health status of the equipment and decide whether repairs or component replacements are necessary. For example, a low health status score indicates significant damage requiring repair or inspection, while a high score suggests good equipment health, potentially eliminating the need for immediate intervention. This health assessment score system provides a quantitative reference for equipment management.
[0057] In summary, the damage assessment method for pressure swing adsorption (PSA) devices provided in this application has the following technical effects: It collects real-time operating data of the PSA device through a sensor system, inputs the operating data into a damage assessment model to monitor the PSA device's condition, and obtains the condition monitoring results; it identifies damage patterns based on the monitoring results in the condition monitoring results to obtain damage pattern data; it assesses the health status based on the damage pattern data to obtain health assessment results; and it continuously monitors the PSA device based on the health assessment results. In other words, by achieving the technical goal of multimodal quantitative detection, it comprehensively and accurately monitors adsorber damage, improves the reliability of damage identification, and thus effectively extends the equipment's service life and ensures safe operation.
